Late last night, AT&T began promoting its new "Next" smartphone upgrade plan in earnest. And earlier yesterday, a leaked training document revealed Verizon's "Edge" upgrade plan. Both are very obvious four-letter copies of T-Mobile's new Jump plan. Let me give you the breakdown on these Jump competitors as quickly as I can.

AT&T will allow you to finance (0% interest, no down payment, no finance charges) a phone for 20 months, pay it off monthly, and after 12 months of payments, will let you trade it in and start financing a new phone, and remaining payments on the old phone will be forgiven.
